GT 7.7 AMOLED producing similar issues as the SGS2 and SGN - Galaxy Tab 7.7 General

Here we go again, looks like Samsung hasn't really fixed any of the 'issues' with the AMOLED display.
I can clearly see the bottom half of my 7.7 has a heavy yellow tint compared to the top half which is whiteish.
Anyone else noticing the same?

My screen has no issues whatsoever, so far as I can tell. I just checked on a grey background to see if I could detect the yellow tint, and nope, it was clean and uniformly grey for me.

Mine is okay too. No issues.

This being my first amoled display - I was blissfully unaware of "limitations" of this new technology. So I had mine on full brightness ( 70 -90%) for the first week I would say
Then I read some other posts like ths - then realised this was not a good thing to be doing. Its like plasma technology (although much better than lcd/led in terms of picture quality) it still suffers with the "image burn in" with static content. It took about 9 generations of plasmas to "cope" with this issue.
SO i would not recommend high brightness for the first week to two weeks to allow the screen to "bed-in" but I am not sure of how oleds function or they even need this.
I do have a very faint yellow hue that matches exactly with the system bar at the bottom. But off course the system bar is static and hides this all together. The problem is when you change oreintations - mine is 99% in landscape so not noticeable for my use.
However in portrait, this again is only really visible on a minimum brightness setting and against dull grey background. If I put up the brightness up to 25% it is really difficult to make out & any brighter I cant see it.
If it bothers you enough then to minimise static content:
1) Screen timeout from 1 - 15 minutes
2) I also now use "hidebar.apk" to hide the system bar. Can be a bit buggy but works on the whole and is free. Use it mainly when browsing for a long periods of time.
3) in the default browser you can change to full screen mode, in settings go to Labs -> select quick controls. This gets rid of the bar at the top.
Finally, full screen web browsing !! Also the quick controls are slick, once you get the hang of it. Just press on the extreme edges of the screen to bring it up.
Or just get a replacement. In your case it sounds bad enough.
For me I cant notice any issue 99% of the time. Even If I knew about the issue beforehand, I think the screen is just way better than anything out there for at least a year or two. You cant fault the rest of the tab - its pretty mint

just so people are aware, this screens "issues" are only for the neat pickers, they are not visible under normal usage condition when the screen is set to auto or manual
the only way to see those is when you set the brightness all the way to Zero
as long as you keep brightness at 20% or more you wont see any of that

Is this the same issue with the Galaxy S1?
On the bottom half I have an area that is yellowish on white pages. And when you look at a black image in a dark room the black on that area is more dark.
When you turn the display off and look against the sun or similar bright light source at a shallow angle you can see that the golden mesh is not flat in this area. it is bumpy

For me there is a huge difference between not having any of those screen issues and saying 'its only visible when X is done'. I prefer to have a flawless screen If I decide to purchase, the money back guarantee / refunds are there for a reason.
I use autobrightness as well and it does drop to 0% when Im using my device in the bed room with the lights off. of course I dont have a Tab 7.7 yet but this is how its been since my Galaxy S days and I've never had to do certain things to prevent flaws from surfacing, it was just flawless to begin with aside from the Pentile limitations on the text.
Then again your opinion, my opinion. I hope to see a flawless screen on the Tab 7.7 though but Im not expecting much.
But we shall see once its locally available.

Dude, the 7.0+ is probably better option for you. Save some money and headache because the technology is samoled+ not ++ or whatever the next generation is going to be called in 12 months.
I would say "normal" usage patterns and many will have flawless screens. Blast it at 100% brightness with a static image for a week - you will not be a happy bunny

Many will have flawless screens but you advise against it
I'll just have to wait for one that is flawless and purchase it, putting the stock keyboard in landscape mode easily shows this issue. For what its worth this yellow tint no matter how slight will show up in HD movies
Even with my phones Im more of an indoors user so my brightness stays either auto or probably fixed at 20% and I usally drop to 0% when web browsing in bed.
But I'll have to see it in person.. or its another refund process.
EDIT:
Believe it or not some review reviews on the Galaxy S2 and Galaxy Note in HD format actually shows a noticeable hint of yellow tinting.. I've seen 2 HD reviews/previews so far and it looks good. Hopefully it translates well in real life.

dont get me wrong. all i am saying that for me i have to go through the following to see something.
1) reduce brightness to 0%.
2) use third party app to dim screen below normal brightness threshold.
3) use third party app to remove system bar
4) change background to a dull grey
so it all depends on ur definition of flawless.
as i say under normal circumstances it is a non issue.

For me its just a 3 step process
1.) set the brightness to 0%
2.) pop out the stock keyboard which is already grey
3.) check for color uniformity
Heres an example on my Galaxy Note: I've cropped the pictures and its a little misaligned be the judge if Im nitpicking or not.
My 'normal' conditions involve using the tab at 0% brightness in about 85% of the time. But I'll have to see it in person to judge but going with that you said then maybe the RGB stripe handles discolorations a bit better.

What am I supposed to see?
I can see that the left part looks "normal" and the right half has yellowish gray colors.

oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

Weird screen issue, confirmed on two so far.

I don't know if these if happening on all our s2's.
basically, I noticed brightness goes down when displaying a lot of whites. e.g. google vs the whites in a page with more darker areas. (i don't think it's my eyes.)
I've never noticed this on my hd2, or any other phones.
when displaying google's in the browser, the white is not impressive at all.
another test i did was with an image I created (attached), half black half white. open in gallery and slide it so more black shows, or more white shows. The whole screen changes brightness!
My friend's S2 does the same.
can anyone confirm?

That's actually a power-saving feature you can turn off.
Go into Settings -> Display -> Scroll down and untick 'Auto adjust screen power'.

Its not.
Its definitely there irrespective of display settings.
Basically even when you are not moving picture, have a look near the border.
There is definite grey banding near the border. It kinda looks like white is bleeding into the black.
And its there on every SGS2, every single one. It can be hardware or software issue.
@OP. you are definitely not alone. I was actually having talk with my friends in UK. 6 of us now have SGS2. 2 are from O2, 3 from P4U and 1 from Handtec and mine is from Clove.
All are experiencing same thing. Its definitely not your eyes.
@others. Its not a glaring issue. You wont notice i t unless there is extreme contrast images on screen like this one. My dad still couldnt notice it when I was showing it to him. But its still there. Will upload video, but its hard to pick on video as well.
It's an option in the Display settings - auto adjust screen brightness after analysing image or something similar.
Samsung thing, I think, since my Omnia 7 with Windows Phone did exactly the same thing. It's trying to save you power and completely normal.

Thanks very much guys, I think I can accept it if it's all built like that. With that option off it really helped! (I feel a lil retarded now). But for some reason that test image I made still has that dimming effect (double tap it in the gallery, this instant change makes it obvious), but maybe that's normal, not fussed. (normal web browsing is perfect)
And no I didn't exchange any phones. Mine does have a dead pixel tho. Can anyone check their screens for dead pixels for me? I know someone had blue lines and stuff on their units, that's a bit drastic. I'm just wondering how many actually have say 1 dead pixel, so I have a better picture before I actually exchange mine or something.
asefsef said:
Yea, I've already got that turned off including power saving mode (mentioned in first post).

Nah, no dead pixels or other screen issues here. If you have dead pixel, i would return it.
Here is the video, its not clear as camera limitations dont really show it properly, but at 720P you can see it for fraction of second, that is not the lens glare but screen turning grey right above the white border.
http://www.youtube.com/watch?v=zGr7xJ1JIjU
around 0:15-0-18 in that video.
As mentioned, its a power saving feature as AMOLED screens don't like whites as they drain power, they prefer blacks. So reducing the brightness helps to save battery.

I can see it grey in the video, almost like that gingerbread scroll limit effect. very hard to see in the video though, would have just said it was the camera.
Yea I'm considering returning. In my other post, I mentioned how Handtec got back to me. In short, not fault since only 1 pixel, but told me I can exchange/return within 7 days. But, they said since it's not a fault, I'll have to pay shipping both ways. (£28 per way, ouch)
Does that sound right??
Just a thought, could not the grey area when moving a black/white border area simply be the screen pixels taking a few milliseconds to go from completely dim, to grey, then to completely white, ie just a response time, albeit a bit slower than what I would have guessed?
On my SGS, going into a completely black app drawer with bright icons and moving around, it also has a very slight dragging effect on some white/black constrasting areas?

Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:

I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.
Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.
B
The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.
I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.
Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.
Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!
As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>
I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?
Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.
so do you think it's a hardware issue, or maybe it will be gone??

When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

This what you mean?
My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.
I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.
I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?
Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

Galaxy S2 Weird Screenburn issue

Ive had this powerhouse of a phone for just under 16 Hours, Screen has only been used for around half an hour etc,
Ive just noticed some screenburn on the screen The four buttons - (Phone, Contacts, Messaging, Apps) are visible on the screen when I look at a grey-ish background (Such as the speedx initial bg). Ive been through 6 Galaxy S2s, Three of them had this issue - Is it me, or is this a bit weird? Phone screen on for only 30mins since it was factory shiny&new, and theres already light screenburn.
Is this a characteristic of SAMOLED Plus, or is this a faultly batch? (Im on my 5th replacement phone from Amazon due to various faults). It seems a bit weird, a phone thats cost near £475 inc has this kind of issue.
Thanks In Advance,
Aman.
(Picture attached, You have to look quite carefully to see the greyish outlines of the boxes)
It doesn't look screen burn as it looks coloured. it might be the app you are running has transparency.
afaik, OLED does suffer from screen burn like plasmas do - potentially, but not that quick!
Well, it can happen. After a month i started seeing the same thing when pulling down the notification bar. So it's not app related, cause i don't use other launcher, i can clearly see the shadow of the 4 icons for a few seconds when pulling down the notification bar. They disappear pretty quickly, i'm not that bothered about that.
Also notice even if you just got the phone the very first second the digital clock actually burns through the notification tray and slowly disappears, I think its a technology limitation on the SAMOLED+
hi i dont know if my post will help or not
put i have a samilliar proplem with my sgs2 screen
i have proplems with colors like grey and dark blue
i will attack photos for u to see if u have the same proplem with colors like me
and my phone is only 14 day old
i really dont know if the colors are normal or not
p.s: make ur display 60/100 to see the colors
on my sgs1 the screen was way better
the first two pics are of the grey color ( to see if u have the same like this pic open msg and write a messege there is an option to write sound messege click on it
it will show the same thing see if u have the same like me
and the third pic is of the home screen to compare see if there is something wrong with ur screen
also could some one please look at his device and my pictures so i can now if there is something wrong with my device
thanks alot in advance

Seems like a SAMOLED+ limitation as you say. I was just curious, it shouldnt bother me much whilst im using my phone normally.

If the screenburn gets really bad, I suppose i can always just use the 2yr Warranty I have on the phone to get the screen replaced. Waste of an invisibleshield though.
Considering the phone is less than a day old, the screen might go really weird in 2-3 months - Which is what im worried about.

I would have to agree that the S1 screen is was a better display even if did have a more jagged edges on the fonts.
I have a similar issue in the messaging app, but with the keyboard. If I 'enable'(/turn on/whatever) it then disable it, it's 'shadow' stays there for a couple of seconds. It is however not a permanent burn in, so I think it's just the screen's limitation and it doesn't really bother me as this screen is still by far the best I've ever used.

wouldn't that screw up video playback though? sounds more like a software bug
I turned the clock on the notification bar back to 24hr , as i read/saw the AM/PM can burn in as they are displayed a lot longer then the 24hr digits which move at least every hour.
I just discovered this issue last night. I had been noticing a few lines here and there on my regular usage and I thought it was just a defective screen. Through the use of Terminal's blue screen, I realized that it wasn't defective.
I have a car dock, and use PowerAMP in the car every day. As you can see above, those burn ins are the buttons in PowerAMP. I went to take a picture of my SGS2 with my N1, and while looking at the blue screen on my SGS2 through the display of the N1, I noticed the N1 had the issue too!
I'm trying to run JScreenFix now to see if it solves the problem, but I highly doubt it.
Will Samsung even honour the warranty for things like this?
I have an SGS1 of 1 year old and my SGS 2 bought in may. Side by side, I will never exchange my SGS2 for another SGS1. Screen quality (colours and details) is by far better on SGS2. No comparision
I also don't see any burn in in both devices (keybord test, status bar...). Maybe some defective devices around that you just should exchange
If you want to test your screen or anything on your phone type *#0*# into the keypad
If the burn don't show up on green blue or red then its something else
I also have the same issue. I can see shadow of the System task bar. It was quite vivid on RED and it shows as lighter blue on blue colour. And on white it became pale white. Bright yellow as well on yellow.
I've tried various things like put the screen on full brightness on Black and Red and blue but still have the shadow there.
I will see if i can get my warranty repair.
I just wanted to confirm that the SGS2 sure can have a Burn In, as it was declared before as "Burn In Proof".
I noticed it while playing the recently released Game "Osmos HD". The game's color temperature is pretty blue-dark, and thats where I can see a slight burn in of the Task Bar.
Afterwards I checked my screen with various LCD Test programs and BAM - with low brightness I see slight burn in of the whole task bar. I can even see the signal indicator, the battery percentage and the spot where the clock sits.
But its only visible at very low brightness and a blue-purple coloring.
I called my brother, who has the Galaxy S2 as well, and he directly went and checked with LCD Tester as well. He, too, reported to me that he also has a slight screen burn in of the task bar, tho its very tough to spot. I guess, if you dont know its there, u wont notice it.
We both have our SGS2 models now for roughly a year, and the screens already seem to decrease in quality and stability.
I am a fan of Super AMOLED+ color quality and contrasts, but my 2 bothers and me have all the yellow tint issue, tho its not very drastic, and all devices start to get kind of a permanent screen burn in.
Its really sad to see that the otherwise fabulous screens already show its age. I hoped that Samsung learned from the SGS1's issues and user feedback, but sadly, it seems like they kind of ignored the fact that the Super AMOLED cant take much action...
My girlfriends Desire HD's screen (which was my phone before I got the SGS2) is still showing good colors. Sometimes I think about getting an LCD device again...
I think what most posters in this thread are reporting is Samoled ghosting, ie image retention for a few secs. Its not permanent, unlike burn-in, which some people may experience after some months of usage.

No, its not ghosting at all.
The taskbar image thats burned in is from MIUI. And since I am running either and Sammy ICS Build or Androidmeda for a while now, this image must've been there for longer than I thought.
As I said, I just noticed it yesterday while trying out the Osmos HD Demo. And its clearly the MIUI taskbar. Must be there for more than a couple of days already.
No screen burn on my Galaxy S2! Btw, been comparing screen to iphone 4/4s and Galaxy S2 screen way better! You have to have some sort of "telescopic" vision to notice resolution advantige on 4s... Who anyway reads webpages fully zoomed out? LoL... With magnifyng glass?? Contrast and colors advantige is huge on galaxy side....

For how long are you using ur Galaxy S2 now? Mine is running non-stop since a roughly a year now.
And yes, it seems like a permanent screen burn in on my end. Just checked again, same visibility of the probably weeks-old MIUI taskbar.

Screen feedbacks/issues

For the current owners, especially for those who are 'extremely' particular about the screen, do you guys any screen related issues?
I've been with the Galaxy S1 and S8500, both devices used the first generation SAMOLED screen and I never had any screen related issues on both devices but as of late there's been a lot of screen issues ( mostly quality control related ) on the Galaxy S2, Galaxy Note and Galaxy Nexus..
To name a few:
- faint but visible horizontal/vertical lines visible on white/grey images
- green/blue color tint when the device is tilted with in just a few degree's
- uneven screen brightness
- suction cup rings
- blotchy/spotty blacks, you can see darker or brighter spots when the screen is displaying an entire black image - All Tab7.7's have spotty blacks, if anyone has a screen w/o spotty blacks please post it up here, it would help a lot of people.
I owned a Galaxy S2, replaced for a total of 7 times all had different screen related issues and I decided to get a refund for and got the G-Note when It came out, already had 1 screen replacement which resolved the lines issue but other screen related issues took its place, still waiting for the 3rd screen replacement to arrive and also processing a refund if they are not able to fix it.
I plan to make the Tab7.7 as my primary media device ( please spare me the 'get a plasma tv defense' ) and a web browsing device so screen quality is very important to me and most of the time it will be used at 0-10% screen brightness in a dark room (bed room).
Using the Tab in a totally dark room is nothing considered as 'extreme conditions' just because not everyone has the same usage pattern does not translate to 'extreme conditions only' situation.
Id like to ask a very honest and objective feedback from the current owners, I also understand that as of now only a few have this device. Testing in a dark room or with minimal ambient light is preferred as reflections can really skew results.
For anyone also wanting to contribute check the following images on your Tab 7.7 and put it in full screen and see if there are any uneven shades,lines or anything to report about.
This thread will get more exposure as the Tab 7.7 is slowly rolled out around the world. I would like to restate that this is purely an objective thread and not the subjective 'i dont see it in normal use' because not everyone has the same normal usage. Its not to say that all of the Tab7.7 screens are defective but Id like to see how wide spread the issue is based on XDA-Developer members. Again people, objective and not subjective.
EDIT:
For now it seems that I've gotten enough feedback and expect the very same issues from the Galaxy S2, Need a huge amount of luck for the purchase on my end.
EDIT2:
We need someone who claims that their black screen output is very uniform and does not have any spots, so far nobody has posted yet but we do see claims but these claims are not enough, for the sake of research anyone with an screen with no blotches or spots on black post up.
EDIT3: (Feb 19 2012)
After checking out and screening a total of 15 units from different stores and different dates, I've managed to see only 2 units with 'acceptable' screens. I say acceptable because I am expecting the grey rendering to be as good as on the Galaxy S and S8500. I will be getting one tomorrow but it still has a visible darker top part and lighter bottom when rendering greys.
The very common issue I've seen is a visible thick vertical/horizontal lines on the screen when rendering greys and either a yellowish or greenish discoloration at the bottom and some reddish bleeding on the edges ( mostly top ) I dont think a screen that can render greys on the Tab7.7 exists for now but Im sure it will be possible 6-8 months down the road when screen production gets better.
Different shades of greys are my objective way of testing the screen quality as it easily cuts down the time needed to do so, if a certain screen passes my objective test I goto the subjective test, Load up Thumbkeyboard and use the split lay out with the ICS theme and observe if the shades on the letters from Q to P are the same, some screens that fail the objective test actually produce good results on the subjective test, while others really give out a very obvious discoloration, also all of my tests are done with 0% brightness since thats the brightness i will be using 90% of the time, as the brightness ramps up these discolorations become less obvious.
EDIT4:
Anyone wanting to set here my suite of grey test images
http://www.mediafire.com/?hfxjz8nhymc4h4d
Crucial images are the grey-15 and grey-25, test in a room w/o any directly light or reflections from your face. 0-33% brightness.

Why grey images, why all this specific settings that require planetary alignment and a virgin sacrifice, read on:-

EarlZ said:
I've had mine for almost a month, no burn-in issues, Ive been using the Tab almost in portrait mode and stopped using Honeybar just to see how fast the burn-in kicks in, nothing what so ever.
I cant judge if its visible in normal use or not, unlike others I dont assume how a screen issue looks like unless I've seen it or at least pictures of the issue, this has always been the source of many arguments in forums, people just assume all screens are created equally and just because they dont see the exact same issue on their end they actually become more aggressive and hateful and they tend to find the need to keep defending the product. What gives?
Companies always add a cost buffer to cover for returns and that is usually with upto 3 returns, but complacent people just accepting obivous defects are also the cause for this level of quality control since Samsung can now get away with it, especially that some people are false advocating that there are issues thats normal to AMOLED which is incorrect.
I havent used my Tab yet as an ebook reader so Im not exactly sure what they are experiencing but the pictures posted paint a clear picture, It can be annoying at times I suppose and when a product is marketed for its great screen and deep black levels, should anything less be expected? I mean personally coming from a Galaxy S which had none of the screen issues you've mentioned, the Tab7.7's screen should be expected to be better in every single aspect, right?
I've been quite active in this forum and I haven't seen anyone report multiple exchanges yet, I didnt even exchange my Tab yet.
I dont know who you are specifically referring to but I also use greys as my test images, let me give you a little more perspective incase you made a 'selective reading' in regards to this issue.
Grey colors easily allow you to check if your getting a quality screen or not, they can easily show those lines and discolorations with out the need for using multiple test images, they give you objective results especially when your buying the device but its not very conclusive since the store light will show a lot of reflection on the screen.
Testing at 0% brightness in low light environment is also ideal for an objective testing to avoid any reflections that you might see hiding these flaws, but if one exclusively uses the device in a very bright environment then this step can be skipped.
And this is the real world perspective:
This is the original grey image:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and it should look close to that on the tablet.. For comparison, on my Galaxy S and my former Galaxy S2 can render this color perfectly.
not something like this:
one side is darker, visible lines, dots, circle marks.
You can argue that it only affects greys but it does affect a lot of things you see on the screen and to a certain extent like this:
and when we flip the tab over we get this:
Ignore the moire, notice that one side is darker than the other.
This is how the original frame looks like:
Sure not everyone uses the Tab7.7 as a media player, remember those visible rings and spots above? Check out the attached images.
This is because reviewers hype up the black levels saying its totally black and some internet articles say that AMOLED is in an 'off' state when displaying blacks which gives us the false information and relatively ruining expectations, my first samoled device was the S8500 (Wave) and the blacks were great, no blobs or spots and it had a very faint glow, that was the foundation of my expectation which was further reinforced by the Galaxy S that gave the same results. Others may have started with the Galaxy S2 and the expectations set by reviewers so they ended up returning their devices. On my end I returned it for the yellow tint, which the technician also confirmed that it was very visible and during that time there was nothing they can do.
Sorry for the wall of text but I felt that I should be explain this thoroughly as I am very affected by the screen issues and I am very vocal about it and it did get things done on my end.
TL;DR
Bottom line is, its a $700 device with its primary feature as the screen which is advertized,marketed and specified to have the most vivid, crisp, sharp and clear images. Others are reporting that they dont have any screen issues-what-so ever so why should someone else for settle anything less?

the 77 has same screen as the note... but it's brightness more even across the screen.. the only problem you will have is it's size... since you're coming from Note.. you might find it hard to justified it's size... like bringing it with u anywhere.? when jogging?

Erm, wrong...
The Note is a PenTile display. The 7.7 is not.
The Note's PenTile arrangement uses 8 subpixels per 1 pixel.
The 7.7's SAMOLED Plus display uses 12 subpixels per 1 pixel.
I won't be brining it around for joggin of that sort, its gonna be my primary media device so it needs defect free from those random manufacturing faults.
It might be too early to ask this as probably the user count in xda is pretty small.
I'm returning one of this beacuse when reading in a dark room there are serval visible rings and spots darker than the rest of the screen.
You are only able to see it when you have a grey or black background and your eyes are adapted to the darkness.

This device probably isn't for you, yet.
I just got the 7.7 and have issues. The brightness is a bit brighter along one side, and I have the dark spot issue, this time in the form of dark circles, equally spaced (probably from the glass handling suction cups or something)
On the bright side, at least I don't have any bad pixels ;/
BTW a good app for testing is the simple "Advanced task manager" app, it has a dark screen near black and these blotches are visible with this even in a room with some light.
I used my galaxy tab 7.7 for almost a month and i must say , the dark circles are truly annoying especially when you watch movies with dark scenes in a dark room with low brightness.You can hide the dark circles by increasing the brightness but it is a simple waste of battery life and its really bright in dark room. I also noticed screen burn in for the wifi and battery icon, i used my 7.7 on zero brightness since day 1 and screen burn-in still persist after 3 weeks. Good way to see the dark circles is by simply turning off the tablet, the tablet will "glow" with the dark circles after the samsung logo is gone.

My old and new one have these rings. I'm guessing its glue or something bonding the screen to a backplate. Or an imprint of a backplate on the screen.
In any case I think this is not a problem or defect. You really must be in total darkness and viewing a black screen to see it. And even then its very hard to see.

Thanks for the heads up, It would seem that the darker spots are quite obvious since the screen is bigger, I also had those spots on some of my Galaxy S2 replacements and I found it very unacceptable and the same with my Note.
When I was testing at the store which had the usual store lighting one unit had several visible lines in greys while the other one only had 3 lines just in the middle.
For the uneven brightness on the screen, Im pretty sensitive to that.. when I saw the HC task bar in landscape mode I immediately noticed a difference in brightness but only 1 of the 2 exhibited the issue.
The screen burn-in is a concern as Im getting the same feedback from friends who bought the unit just last week!
I understand that not all screens have this issue but the chances of getting an out of spec screen might be pretty high, wish they brought back the same quality control when the Galaxy S initially came out, which had none of these issues what so ever.

It is a defect and a very bad one, also the visibility on this is not the same on all units. I have a suction up ring on my Galaxy Note which is visible at the 'service center lighting conditions' which the tech also saw the rings. Several pictures of this issue also posted on the various Galaxy S2 forums here in XDA under a well lit condition.

Seems like it until screen yields improve or I get a chance to get one w/o any of these out of spec issues.
No screen is perfect, not even the ipad screen.
Ihave a galaxy s2 and rememeber hearing all the burn in worries last year. Almost a year later now and i dont have any burn in.
The only issue ive noticed is that some pixels on oled can have a slightly differrent brightness than others due to the nature of oled. Yes my s2 has a tiny amount of pixels like that,
But you have to look at it at the wrong angle with the wrong amount of ambient light with the wrong colour on the screen to notice it.
Yes a larger screen is likely to have more issues but if it was an ips screen then we would no doubt all complain about backlight bleed.
My advice is stop looking for problems with it and enjoy your tablet otherwise you will never be happy with it !

Like what you said, no perfect screen but there are some screens that are made better, A year of usage with no burn-in is fantastic! Some are getting it as early 30days from purchase.

The only issue ive noticed is that some pixels on oled can have a slightly differrent brightness than others due to the nature of oled. Yes my s2 has a tiny amount of pixels like that,

Yes to certain degree there are but they should not be noticeable to the naked eye, if its noticeable then its purely a quality control issue.

But you have to look at it at the wrong angle with the wrong amount of ambient light with the wrong colour on the screen to notice it.

Well that depends on the usage, Im not pushing my own usage to anyone as I believe not everyone watches movies or browses the web on the tab7.7 with close to 0% brightness and in total darkness. My usage revolves on that so there are no special conditions on my end. I hope this is understandable.

Yes a larger screen is likely to have more issues but it was an ips screen then we woukd no doubt all complsin abiut backlight bleed.

I do not look for these issues intentionally and I see them with my normal usage, thats why I intend to research first before taking the plunge. But I understand I might have a higher standards that others but thats just me, I want to get the most of my purchase or not purchase at all.
Long story short, all the screen issues I've found on my Galaxy S2 was due to normal usage including the yellow tinting and darker spots which annoyed the heck out of me considering the cost of the device. On the Galaxy Note I've read about the all the screen related issues even on the video issue and still said to my self 'these things should not be noticeable in normal usage' but i was wrong. So this time Im taking it slowly but I already know what to expect. But I do understand what you are trying to say.
EDIT:
I dont want anyone to mistake this as a witch hunt, I just want to know what to expect, acceptance is easier when expectations are set.
Yes, there will never be 100% perfect screens. We'd all be constantly returning devices and not actually using them because of some "defect".
I've had my S2 since it first came out in May 2011. No problems with burn-in or colour shifts. I don't expect my 7.7 to have problems either. I'm not concerned that some "defect" will manifest itself under some extreme "only if I go looking " condition.
I'm enjoying using my S2, 7.7, and Transformer for what they are - mobile devices that provide communications, entertainment, and information.
Agreed I can also accept defects as long as I dont see them with my usage. Example between my SGS2 vs Galaxy Note which shared a common issue on the darker spots but it was more obvious on the SGS2 since it was a horrible pattern while on the Galaxy Note its tiny and multiple spots.
Every defect is different and we should not all assume that they are all acceptable to everyone.

May be for you it's an extreme situation, but in my case, I bought this tablet for reading ebooks at bed (among other things) and I use white text over black background, so I am in that "extreme situation" on a daily basis.
I also have a Galaxy Nexus and that screen also have one line and some dots, but since my usage pattern is not the same it don't bothers because I really dont see it. But in the case of the tablet, I had to convince myself that I had paid a big amount of money to receive a screen with what for me is a defect.
I was the owner of a Huawei Ideos S7-105 (I now miss it) and appart from the battery and several other small annoyances I was pretty happy with it, I paid 150€ for it so I got what I paid for, but the 7.7 costs 450€ so my level of exigence is higher.
Sad thing abot all of this is that the other tablet that could be an option (Xoom 2 8.2) seems to bee plently of issues as well.

This is always the case, people who dont have the same usage pattern nor with the same issue will never understand. But its been my understanding that this is already 'common' (but not normal) among amongst the hd samoled and samoled plus.

Yes the other alternatives that I've been looking are also riddled with issues, come to think of it only samsung has the least issues based on my research.
I've seen the concerns on other AMOLED devices Earlz mentions as well.
It's not a deal beaker but you may want to keep a LCD device around for reading at night.
No use exchanging numerous times hoping for a perfect screen.
Right now while AMOLED is a very dramatic screen tech
but it's not at its best with low brightness levels,
and certain test patterns / images reveal other side effects .
For reading in the dark a screen like the iPad 2's IPS LCD is probably a better choice.
It offers a very low brightness level with consistent results.
I think the key is to use AMOLED devices where they perform best,
at higher brightness levels during the day.
In that scenario if you hand a iPad 2 and AMOLED device
to the average person they will be floored with the AMOLED screen.
I don't have any issue on low brightness level.
I always operate my 7.7 at ~0-20% brightness.
Did anyone test the screen using the screen test apps? I tested mine and I have yellowish patch at the bottom part of the screen. It's only visible in dim grey. Luckily there is no dead pixel but my screen start to squeak a little when press at the bottom corner. The quality control is really bad. I'm waiting for a engineering revision before going for warranty claim. I must say I'm disappointed.

There's been a few reports from here and another forum that the screen seems to squeak or dislodge a bit on the bottom corner.
@SonicTab:
I went for an amoled screen beause it's suposed that when screen is black pixels are off and there should be no light emiting so in my case, when reading in the dark I should only see the text, and not a bluish black background as every other LCD based screen
@GOF007:
You are either lucky or do not use the tablet in the same conditions as I do. Did you test it viewing one of the pictures in the first post in a dark room?
I really hope my case where just bad luck and be given another tablet whitout those screen issues, or at least with something less annoying.
